Mistuning perception in music is asymmetric and relies on both beats and inharmonicity [PDF]
Communications PsychologyAn out-of-tune singer or instrument can ruin the enjoyment of music. However, there is disagreement on how we perceive mistuning in natural music settings. To address this question, we presented listeners with in-tune and out-of-tune passages of two-part

A novel mathematical model for the design of the resonance mechanism of an intentional mistuning bladed disk system [PDF]
Mechanical Sciences, 2022 Bladed disk systems with advanced functions are widely used in turbo-machineries. However, there are always deviations in physical dynamic properties between blades and blades due to the tolerance and wear in operation.

Key Action Mechanisms of Intentional Mistuning
Applied Sciences, 2021 Intentional mistuning is a common procedure to decrease the uncontrolled vibration amplification effects of the (unavoidable) random mistuning, and to reduce the sensitivity to it.

Effect of mistuning parameters on dynamic characteristics of mistuned bladed disk [PDF]
Journal of Vibroengineering, 2021 The aim of this paper is to study the nonlinear dynamics of the tenon and mortise of aero-engine compressor blades, based on lumped parameter model of tenon and mortise of blade disk system, considering the influence of gap and friction, The nonlinear vibration characteristics of mistuned bladed disk with different mistuning parameters are studied. The

Journal of Low Frequency Noise, Vibration and Active Control, 2021 Blade crack will cause severe mistuning of hard-coated blisks, which will lead to vibration localization. To identify crack mistuning and analyze influence factors, in this study, a mistuning identification method of blade cracks in hard-coated blisks is

Robustness of learning that is based on covariance-driven synaptic plasticity. [PDF]
PLoS Computational Biology, 2008 It is widely believed that learning is due, at least in part, to long-lasting modifications of the strengths of synapses in the brain. Theoretical studies have shown that a family of synaptic plasticity rules, in which synaptic changes are driven by ...

Characterization of the Anomalous Vibration Response of an Intentionally Mistuned LPT Rotor
Machines, 2022 The wind tunnel facility at the Centro de Tecnologías Aeronáuticas was used to perform a set of experiments to study the effect of intentional mistuning on the forced response behavior of an aerodynamically unstable low-pressure turbine rotor.

A Modal Interpretation for Aeroelastic Stability Enhancement of Mistuned Bladed Disks
Aerospace, 2022 Understanding the mechanism of the aeroelastic stability improvement induced by mistuning is essential for the design of bladed disks in aero-engines. In this paper, a quantitative interpretation is given. It starts by projecting the mistuned aeroelastic
